BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to quinoline derivatives and quinazoline derivatives and more particularly to quinoline derivatives and quinazoline derivatives that can be used in the treatment of diseases associated with the autophosphorylation of a PDGF receptor and particularly can inhibit angiostenosis.

[0003] 2. Background Art

[0004] PTCA (percutaneous transluminal coronary angioplasty) is widely adopted as therapy useful for ischemic heart diseases resulting from coronary stenosis. Vascular restenosis, which is observed in a frequency of about 30% within 3 to 6 months after the operation of PTCA, however, has become a serious problem associated with long-term prognosis and medical economy. The restenosis is considered attributable to the fact that vascular smooth muscular cells or fibroblasts of the vascular outer membrane are activated, for example, by platelet activation caused by the tear of vascular tunica intima or media, extension stimulation, and vascular endothelial cell injury at the time of catheter therapy and consequently migrate and proliferate and excessively accumulate at injured vascular sites.

[0005] Various growth factors have hitherto been assumed as the vascular smooth muscle cells or fibroblasts activation factors. In particular, since R. Ross et al. have proposed a hypothesis of a injury reaction (N. Engl. J. Med., 295, 369 (1976)), PDGF (platelet-derived growth factor) has drawn attention as one of factors causative of arteriosclerosis and has been also considered as a major factor causative of restenosis from both fundamental and clinical aspects (G. A. A. Ferns et al., Science, 253, 1129 (1991), M. G. Sirois et al., Circulation, 95, 669 (1997), and M. Ueda et al., Am. J. Pathol., 149, 831 (1996) etc.)

[0006] PDGF-R (PDGF receptor) autophosphorylation inhibitory compounds (WO 97/17329 and The FASEB Journal, Vol. 11, pp. 1119-1126 (1997)) have been reported up to now.

[0007] For PDGF receptor autophosphorylation inhibitory compounds which have been reported, however, the selectivity for VEGF receptors (such as KDR) and c-kit (SCF receptors) belonging to the PDGF receptor family has not been discussed.

[0008] VEGF is one of major growth factors of vascular endothelial cells (EC), and VEGF receptor inhibitory compounds possibly inhibit the regeneration of EC in injured blood vessels to promote the formation of thrombus and to accelerate angiostenosis.

[0009] Further, SCF is a growth factor involved in the upstream of hematopoietic system and the movement of intestinal tracts, and substances that inhibit receptors of SCF possibly induce hematopoietic failure and intestinal tract movement failure.

[0010] For these reasons, compounds that can selectively inhibit PDGF receptors for c-kit, KDR, and the like are family are expected as anti-restenosis agents that have no significant side effect.

[0011] Although various restenosis inhibitors have been developed up to now, any pharmaceutical compound having potent angiostenosis inhibitory activity has not yet been developed.

SUMMARY OF THE INVENTION

[0222] Use of Compounds

[0223] The compounds according to the present invention inhibit, in vitro, PDGF-R autophosphorylation and the growth and migration of vascular smooth muscle cells induced by PDGF stimulation (see Pharmacological Test Examples 1 and 2). The autophosphorylation of PDGF receptors mediates diseases, for example, ischemic diseases involving blood vessel occlusion or angiostenosis induced by angiopathy, ischemic diseases involving blood vessel occlusion or angiostenosis induced by vascular autotransplantation or allotransplantation, and diseases involving cell proliferation and organ fibrosis induced by PDGF, for example, chronic rheumatism, PDGF-dependent tumors such as glioma, cirrhosis, pulmonary fibrosis, and occlusion of arteriovenous shunt resulting, for example, from dialysis of patients suffering from renal failure (Gordon A. A. Ferns et al., Science, Vol. 253, pp 1129-1132 (1991), Martin G Sirois et al., Circulation, Vol. 95, No. 3, pp 669-675 (1997), Marukka Myllarniemi et al., The FASEB Journal, Vol. 11, pp 1119-1126 (1997), H. Ohnishi et al., Life Science, Vol. 28, pp 1641-1646 (1981), J. Gastroenterol. Vol. 32, pp 496-501 (1997), Toxicol. Appl. Pharmacol. Vol. 149, pp 120-126 (1998), and Am. J. Pathol. Vol. 148, pp 785-800 (1996)). Further, the compounds according to the present invention have low VEGF-R inhibitory activity (Pharmacological Test Example 5). Compounds, which do not inhibit VEGF-R, are expected not to accelerate angiostenosis. Furthermore, the compounds according to the present invention inhibit, in vivo, neointima formation hypertrophy of injured blood vessels (Pharmacological Test Examples 4 and 6). Therefore, the compounds according to the present invention can be used in the treatment of diseases mediated by the autophosphorylation of PDGF receptors, particularly ischemic diseases involving blood vessel occlusion/angiostenosis induced by blood vessel injury or vascular autotransplantation or allotransplantation.

[0224] The compounds according to the present invention have low c-kit autophosphorylation inhibitory activity.

Therefore, the pharmaceutical composition comprising the compound according to the present invention as active ingredient may be formulated into suitable dosage forms according to the administration routes.

[0226] Specifically, oral preparations include tablets, capsules, powders, granules, and syrups, and parental preparations include injections, suppositories, tapes, and ointments.

[0227] These various preparations may be prepared by conventional methods, for example, with commonly used component, such as excipients, disintegrants, binders, lubricants, colorants, and diluents.

[0230] The dose of the compound according to the present invention in the pharmaceutical composition may vary depending upon the dosage form. In general, however, the dose is about 0.5 to 50% by weight, preferably about 1 to 20% by weight, based on the whole composition.

[0231] The dose may be appropriately determined depending upon, for example, the age, weight, sex, difference in diseases, and severity of condition of patients, and the active ingredient may be administered, for example, in an amount of 0.1 to 100 mg/kg, preferably 0.1 to 30 mg/kg. This dose can be administered at a time daily or divided doses of several times daily.

Pharmacological Test Example 1 Measurement of Inhibitory Activity Against PDGF-Ra Phosphorylation by PDGF-AA Stimulation Using G292

[3948] G-292 human osteosarcoma cells (Dainippon Pharmaceutical Co. Ltd.) were cultured in a DMEM medium (Dainippon Pharmaceutical Co. Ltd.) containing 10% FBS within an incubator containing 5% carbon dioxide until 80% confluent, and the cells were planted at 3×10⁴ cells per well in 96-well flat-bottom plates in the same medium containing 0.1% FBS. After cultivation at 37° C. overnight, a solution of a test compound in dimethyl sulfoxide was added to each well, and a reaction was allowed to proceed at 37° C. for one hr.

[3949] After the reaction of the test compound, PDGF-AA (Upstate) was added to 50 ng/ml, and the cells were stimulated at 37° C. for 5 min. Thereafter, the cells were solubilized and shaken at room temperature for 20 min.

[3950] This solubilized cell solution was transferred to a 96-well plate coated with aniti-phosphotyrosine antibody PY-20, and a reaction was allowed to proceed at 4° C. overnight. Anti-PDGF-Ra (c-20) (Santa Cruz) was added as a primary antibody, and a reaction was allowed to proceed for one hr. GAR (Anti-rabbit Ig, horseradish peroxidase, Amersham) was then added as a secondary antibody, and a reaction was allowed to proceed for one hr. Color development was carried out using a color development kit for peroxidase (Sumitomo Bakelite Co., Ltd.), and the absorbance was measured at 450 nm. The phosphorylation of PDGF-Ra in the presence of the test compound was measured by presuming a phosphorylation degree of the receptor in the presence of a ligand to be 100% and a phosphorylation degree of PDGF-Ra in the absence of a ligand to be 0%, and IC₅₀ was then determined.

Pharmacological Test Example 2 PDGF-R Autophosphorylation Inhibition Screening (Dot Plotting)

[3951] Vascular smooth muscle cells (passage 5 to 10) collected from rat thoracic aorta by the explant method were planted at 8×10³ cells per well in 96-well plates, subject to a serum starvation state, and 24 hr after the plantation then assayed.

[3952] A test compund was added, and the mixture was incubated at 37° C. for one hr. Thereafter, PDGF-BB was added to 50 ng/ml, and the mixture was incubated for 5 min, followed by washing with cold PBS. Lysate buffer (20 μl/well) was then added, SDS buffer (20 ml/well) was added thereto, and 2 μl of the mixture was then spotted on a PDVF membrane.

[3953] Treatment was carried out with anti-mouse IgG which had been labelled with peroxidase after treatment with an anti-phosphotyrosine antibody, followed by development in an ECL color development kit (Amersham). Thereafter, the color intensity was quantitatively determined by image analysis.

[3954] The inhibitory activity IC₅₀ of the test compound was calculated by presuming a color intensity with the addition of PDGF and without the addition of the test compound to be 0% inhibition and a color intensity without the test compound and PDGF to be 100% inhibition.

Pharmacological Test Example 3 Inhibitory Activity Against c-kit Autophosphorylation

[3955] MO7e (human megakaryocytic leukemia cell line) which had been arrested for 20 hr was seeded into 96 well plates at an amount of 2×10⁵ per well. A solution of a test compound in DMSO was added, and a reaction was then allowed to proceed for one hr. Thereafter, the cells were stimulated by 50 ng/ml of h-SCF for 5 min, followed by replacement with lysate buffer to solubilize the cells.

[3956] Next, the solubilized cell sap was transferred to a 96-well plate with an anti-phosphotyrosine antibody (PY-20) previously immobilized thereon, and a reaction was allowed to proceed. Thereafter, the cells were reacted with an anti-c-kit antibody (c-19, Santa Cruz) as a primary antibody and were labelled with GAR (anti-rabbit IgG, horseradish peroxidase, Amersham) as a secondary antibody. Color development was then carried out in a peroxidase color development kit (Sumitomo Bakelite Co., Ltd.), and the absorbance was measured at a wavelength of 450 nm.

[3957] The c-kit autophosphorylation inhibitory activity of the test compound was measured by presuming c-kit autophosphorylation activity with the addition of DMSO in the absence of h-SCF to be 100% inhibition and c-kit autophosphorylation activity with the addition of DMSO in the presence of h-SCF to be 0% inhibition, and IC₅₀ was then determined.

Pharmacological Test Example 4 Rat Carotid Balloon Injury Model

[3959] Wistar male rats (330 to 370 mg) were anesthetized with pentobarbital anesthesia, the right femoral region was incised from the rats, a Fogaty 2F catheter was inserted through the right femoral artery and was led to the left carotid artery, and abrasion was made three times with an expansion diameter of 2.5 mm.

[3960] The test compound was suspended in 1% cremophore, and the suspension was orally administered at 0.4 ml/100 g B.W. twice a day through an oral probe for rats for 2 weeks from the day before an operation. On the second week after the operation, the rats were sacrificed by ether. The left carotid artery was removed and was fixed in buffered formalin. Sliced preparations embedded in paraffin were stained with HE and were subjected to image analysis for the measurement of the neointima area (I) and media area (M) in the section of injured blood vessal. I/M was calculated as an index for the evaluation of drug efficacy.

Pharmacological Test Example 5 Measurement of Inhibitory Activity Against KDR Phosphorylation

[3962] NIH 3T3 cells (Sawano A et al., Cell Growth & Differentiation, 7, 213-221 (1996)) prepared by transfection of human KDR were cultured in a DMEM medium containing 10% FBS (GIBCO BRL) within a 5% carbon dioxide incubator until 50 to 70% confluent. The harvested cells were inoculated into wells of a collagen-type one-coat 96-well flat-bottom plate, each containing the same medium, in an amount of 1.5×10⁴ per well, followed by cultivation at 37° C. overnight. The medium was then replaced by a DMEM medium containing 0.1% FBS. A solution of a test compound in dimethyl sulfoxide was added to each well, and the cultivation was carried out at 37° C. for additional one hr. A human recombinant vascular endothelial growth factor (hereinafter abbreviated to “VEGF”) was added to a concentration of 100 ng/ml, and the stimulation of cells was carried out at 37° C. for 2 min. The medium was removed, the cells were washed with phosphate buffered saline (pH 7.4), and 50 μl of a solubilization buffer (20 mM HEPES (pH 7.4), 150 mM NaCl, 0.2% Triton X-100, 10% glycerol, 5 mM sodium orthovanadylate, 5 mM disodium ethylenediaminetetraacetate, and 2 mM Na₄P₂O₇) was then added thereto. The mixture was shaken at 4° C. for 2 hr to prepare a cell extract.

[3963] An anti-phospho-tyrosine antibody (PY20; Transduction Laboratories) was immobilized on a microplate for ELISA (Maxisorp; NUNC), and the whole quantity of the cell extract was transferred to the wells, and the immobilized antibody was reacted with the phosphorylated protein at 4° C. overnight. After washing, an anti-KDR antibody (Santa Cruz) was allowed to react at room temperature for one hr, and, further, after washing, a peroxidase-labeled anti-rabbit Ig antibody (Amersham) was allowed to react at room temperature for one hr. After washing, a chromophoric substrate for peroxidase (Sumitomo Bakelite Co., Ltd.) was added thereto and was allowed to react at room temperature. After a suitable level of color development, a reaction termination solution was added to stop the reaction, and the absorbance at 450 nm was measured with a microplate reader. The KDR phosphorylation activity for each well was determined by presuming the absorbance with the addition of VEGF and without the addition of the medicament to be 100% KDR phosphorylation activity and the absorbance without the medicament and VEGF to be 0% KDR phosphorylation activity.

[3964] The concentration of the test compound was varied on several levels, the inhibition (%) of KDR phosphorylation was determined for each case, and the concentration of the test compound necessary for inhibiting 50% of KDR phosphorylation (IC₅₀) was calculated.

[3965] The results were as follows. Example No. IC₅₀ (nM) 223 38 287 >1000 408 108 421 692 516 >1000 567 >1000 590 >1000 614 47 615 37 622 >1000 647 599 679 323 687 176

[3966] Edible shoats (24 to 31 kg) were anesthetized with telazol and xylazine, a balloon catheter was inserted through the femoral artery, and the descending branch in front of the heart on the left and the right rotator branch were injured under vasographing.

[3967] For 28 days from the operation, the compound of Example 679 was orally administered as a gelatin capsule at a dose of 10 mg/kg twice a day. Further, only a gelatin capsule was administered as a control. In the test, each group consisted of 6 shoats.

[3968] On the 28th day from the operation, the shoats were sacrificed with pentobarbital and were perfused with buffered formalin, and the heart was then removed. Paraffin embedded preparations of the injured blood vessel portion were sliced and stained with HE, followed by image analysis to measure the intima area (IA), media area (MA), and vessel area (VA), and the fissure length (FL) and vessel perimeter (VP) of the inner elastic plate.

[3969] IA/MA and (IA/VA)/(FL/VP) were calculated as an index for the evaluation of drug efficacy.

[3970] The results were as follows. (IA/VA)/(FL/VP) Dose (mg/kg) IA/MA inhibition (%) inhibition (%) Control — — 10 36 (p < 0.05) 47 (p < 0.001)
